If you haven’t used Instapaper for awhile, it might be time to dig the app out again. It’s just received a great new update to version 6.2, adding some slick features like speed reading, the ability to tweet screenshots of text, and more.

Calling itself a social networking app for just two people, Avocado has long been one of the favorite apps of me and my wife. For everything from sending little reminders of affection in the form of digital hugs, to letting you know when your partner’s phone is about to die, it’s a fantastic Swiss Army knife of tools for people in a relationship.

With Avocado’s 2.1 update, though, that Swiss Army knife has gained one more tool: Google Calendar sync. And it’s about time.

Reeder 2– the best RSS reader on iOS — is getting a beefy new update soon, hopefully in time for holidays. The app’s developer has just submitted an update to Apple for approval that adds some big new features — including themes, Safari Reading List support, and more — as well as tweaked features and a load of bug fixes.

Last month, Facebook released an update that allowed iPhone users to edit posts and comments and even preview all of their changes. It was a small, but welcome update. Unfortunately, it was also exclusive to the iPhone, but now users of Facebook for iPad can avail themselves of the same trick.

Today the GoPro iOS app hit version 2.0, and the update includes several additions that make it easier to interface with the GoPro camera from an iPhone or iPad. The app is way more than a remote control now.

The biggest feature is the ability to wirelessly transfer photo and video from the camera to a dedicated album in an iOS device’s camera roll. Once the you download version 2.0 of the iOS app and the most recent software update for the camera itself, you can browse, view, and delete media right from the camera’s memory card. Photos and videos that have been wirelessly synced over to your iOS device from the camera can be shared through email, text, or other apps like Instagram and Facebook.
